Abstract: The present invention relates to a series clearance multi-point discharging spark plug for a spark ignition engine, including a wiring screw. The wiring screw is arranged in an insulator. A central electrode is arranged in a tip of the insulator. A built-in damping resistor is arranged between the central electrode and the wiring screw. A ceramic multi-point discharging ignition table fitted with the insulator is arranged at a bottom of the insulator. A cavity assembly is formed between the ceramic multi-point discharging ignition table and the insulator. An outer wall at an upper end of the ceramic multi-point discharging ignition table is fastened to the shell. An ignition electrode assembly is arranged at the bottom of the ceramic multi-point discharging ignition table. The series clearance multi-point discharging spark plug increases temperature and pressure of mixed gas during ignition, thereby improving ignition performance, shortening combustion duration and improving engine performance.
